To all whom it may concern.-

Be it known that we, DAVID E. PETERSON, and ISAAC B. BITTER, citizens of the United at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new. and

Quseful Improvements in Freight-Cars, of

which the following is a specification.

Our invention relates to improvements in freight cars and particularly to freight cars used for carrying breakable goods,'and the object of our invention is to construct a freight car with an auxiliary body, which is movable longitudinally, and having means for relieving the auxiliary body of the shock and jar incident to the freight cars contacting with each other during the sudden stopping and starting of the trains; these together with variousothernovel features ofconstruction and arrangement of the parts, which will be more fully hereinafter described and claimed, constitute our invention.

Referring to the accompanying drawings, in which like references refer'to like parts, Figure 1. is alongitudinal section through v the body of the freight car and illustrating our novel improvements; Fig. 2. is a transverse section on line 2--2, Fig. 1. and Fig. 3. is a horizontal section, of one end of the freight car, as on line 3-3, Fig. 2.

In the drawings, 1, represents the body of the freight car which is of the refrigerator type. Our improvements however may be applied to any other form of cars without departing from our invention. The body of the freight car consists of the side and end walls 4 and 5, the floor 6, carried by the sills 7, and the top 8. Ice compartments 9 and 10 are provided at the ends of the car body. An auxiliary body 12, is provided for receiving the goods to be transported.

The auxiliary body 12, consists of the floor 15, and the side'and end walls 16 and 17. The auxiliary body 12, is made slightly narrower than the inside width of the car body 1, and sufliciently shorter in length than the inside length of the car body to permit the auxiliary body to have a longitudinal movement within the car body.

Interposed between the auxiliary body 12, and the floor 6, of the car'body, are a number of sets of rollers and tracks, or cams, which are provided to carry the weight of the auxiliary body and also to permit the latter to move longitudinally in relation to the car body. The said rollers are secured,

either to the car body or to the auxiliary body andthe tracks or cams are secured to the opposite one of the said parts. We prefer .to mount the rollers in bearings secured in the floor of the car body and arrange the tracks or cams upon the bottom of the auxil iary body, as shown in the drawings. The

rollers 20 are mounted loosely upon the shafts 21, which are mounted in bearings 22, secured in the floor 6, of the car, body 1. Upon the under side of the floor 15, of the auxiliary body 12, are secured, tracks or rollers 20, and lift the auxiliary body. As

soon as theefi'ect of the force which moved the auxiliary body has been overcome the weight of the auxiliary body will cause it to resume its normal position upon the rollers. Additional means for reducing the jarring and'also for limiting the movement of the auxiliary body are provided at each end of the car. A resilient buffer 35, is .pivotally mounted at one end thereof ina bearing 36, secured upon the end of the auxiliary body 12, and the opposite end of the bufler 35, is pivotally mounted in a bearing 37, secured to the car body. We prefer to use a buffer of the plunger type, containing a liquid for making a resistance against the movement of the parts in either direction.

The buffers35 are pivotally mounted so iary body in relation to the" body of the freight car. When the auxiliary body has been shifted from its normal position upon the rollers 20, the Weight of the auxiliary body will cause the tracks 30, to slide upon the rollers 20, until the tracks 30, resume the central position upon the rollers and bring the auxiliary body back to its normalposition. The rollers 20, are provided with flanges 24:, so that the tracks 30, will travel in a line parallel with the length of the car and prevent the sides of the auxiliary body .from contacting with the inside surface of the body of the freight car.

Having thus described our invention we claim and desire to secure by Letters Patent;

1. The combination of a car body, an auxiliary body 'movably arranged within said car body, rollers loosely mounted upon one of said bodies, tracks secured upon the opposite one of said bodies, said tracks and said rollers adapted to support the weight of the auxiliary body, and said tracks being inclined obliquely at either side of said rollers to retard the longitudinal movement of the auxiliary body within the car body.

2. The combination of a car body, an auxiliary body movably arranged within said car body, rollers. mounted upon one of said bodies, tracks secured to the opposite one of said bodies, and said tracks forming cam surfaces extending obliquely at either side of said rollers against which said rollers take when the auxiliary body moves' longitudinally in relation tothe car body.

3. The combinationof a car body, an auxiliary body movably arranged Within said car body, rollers loosely mounted upon one of said bodies, and tracks forming double faced cams secured upon the opposite one of said bodies whereby the auxiliary body is raised by the longitudinal movement of the cams in relation to the said rollers.

4. The combination of a car body, an auxiliary body movably arranged Within-said car body, rollers loosely mounted upon one of said bodies, tracks secured upon the opposite one of said bodies, said tracks and said rollers adapted to support the weight of the auxiliary body, form guides for said tracks, and said tracks being inclined obliquely at either side of said rollers to retard the longitudinal movefianges upon said rollers toiaaaeve ment of the auxiliary body within the car body.

5. The combination of a car body, an auxiliary body niovably arranged within said car body, resilient bufi'ers located at either end 'of the auxiliary body, rollers loosely mounted upon one of said bodies, tracks secured upon the opposite one of said bodies, said tracks and said rollers adapted to support the weight of the auxiliary body and said tracks having inclined surfaces at either side of said rollers.

6. The combination of a car body, an auxiliary body mounted within said body and adapted to move longitudinally, resilient buffers located at either end of the auxiliary body, bearings secured to .the car body, bearings secured to the auxiliary body, said buffers pivotally mounted between said bearings, rollers mounted upon one of said bodies, tracks secured upon the opposite one of said bodies, said tracks and said rollers adapted to support the weight of the auxiliary body and said tracks having inclined surfaces at either side of said rollers.

7. The combination of a car body, an auxiliary body movably arranged within said car body, resilient bufiers located at either end of the'auxiliary body, bearings secured to the car body, bearings secured to the auxiliary body, said buffers pivotally mounted between said bearings, tracks secured to the under side of the auxiliary body, rollers secured in bearings upon the floor of the car body, and inclined cam surfaces formed upon said tracks adapted to ride upon said rollers and tend to bring said auxiliary body into its normal position-within the car body. In testimony whereof we haveaflixed our signatures in presence of two Witnesses.
